Abstract
In India, coal is the dominant sources of energy generation. The need and conservation of energy are important. At present 60-62% of total power production in our country is accomplished by the coalfired thermal power plant. In power plant, the power is produced by converting the chemical energy of coal into electrical energy by the generator. Due to the increased steam leakages and damage to turbine components (Blade Failures) resulting in the loss of turbine efficiency. Basically, the thermal power plant works on improved or modified Rankine cycle to run the plant at highest possible efficiency. Based on heat rate values, to improve the turbine efficiency and overall efficiency by determining the optimum process parameter levels in a steam turbine. The optimization of parameter levels is done by using Taguchi's experimental design method, Orthogonal Arrays (OA) of Taguchi's, regression analysis, Signal to Noise (S/N) ratio and are employed to find the optimal process parameter levels and also to analyze the effect of that parameters. A present effect of individual parameters on performance is estimated by using ANOVA. By using ANSYS software the turbine blades stress distribution, deflection, static and fatigue are to be analyzed. By using this technique, within the available sources, the maximum efficiency of the turbine is to be acquired.
